The spur gear 34 is configured to be slidable on the hexagonal shaft 33 along the length direction thereof. Then, normally, a spring 35 provided between the bearing 31 and the bearing 31 urges the bearing 32 side.

The end of the hexagonal shaft 33 on the bearing 32 side projects from the chassis 1, and the bar 10 extending from the chassis 1 to a position higher than the body is attached to this end. On the other hand, a disk-shaped member 36 is attached to the end of the hexagonal shaft 33 on the bearing 31 side. A protrusion 37 is provided at an eccentric position of the disc-shaped member 36, and a spring 38 having one end attached to any position of the chassis 1 is connected to the protrusion 37. The spring 38 urges the protrusion 37 of the disk-shaped member 36 so that it is always positioned above. As a result, the bar 10 will always be oriented perpendicular to the chassis 1. That is, even if the bar 10 is rotated and stopped at a position parallel to the chassis 1, for example, the bar 10 is not rotated by the spring 3.
The elastic force of 8 can return it to a position perpendicular to the chassis 1 and does not interfere with normal traveling.

A steering signal from the control IC 54 is input, for example, a steering drive amplifier 55 that operates the magnetic steering unit 56 to turn the toy vehicle to the left and right,
A drive signal from the control IC 54 is input and a motor drive amplifier 57 that drives the motor 11 to move the automobile toy forward or backward, and a solenoid drive amplifier 59 that receives the control signal from the control IC 54 and energizes the solenoid type electromagnet 41. It consists of

The operation of the automobile toy of the present embodiment having the above configuration will be described in detail with reference to the operation explanatory view of FIG. Note that FIG. 5 is a view of the automobile toy of this embodiment as viewed from the rear.

Normally, in a toy car, the rear wheels are driven by the motor 11 and run while the front wheels 3 and the rear wheels 4 are in contact with each other (FIG. 5 (a)).

While the automobile toy is running, a signal for instructing energization of the solenoid type electromagnet 41 is transmitted from the transmitter to the control unit of the automobile toy. In the control section, this signal is input from the control IC 54 to the solenoid drive amplifier 59, and a current is passed through the solenoid type electromagnet 41 under the control of the solenoid drive amplifier 59. As a result, the iron core inside the solenoid becomes a magnet, and the moving iron core 43 is attracted to the solenoid type electromagnet 41. With the movement of the movable iron core 43, the support member 48 provided on the movable iron core 43 draws the arm 44. As a result, the spur gear 34 is pressed by the lower end portion 45 of the arm 44, overcomes the force of the spring 35, and moves toward the bearing 31. By this movement, the worm gear 15 provided on the shaft 12 and already rotated by the motor 11, and the spur gear 3
4 meshes with each other, and the driving force of the motor 11 causes the hexagonal shaft 33 to rotate. By the rotation of the hexagonal shaft 33, the bar 10 connected to the hexagonal shaft 33 becomes
For example, it rotates clockwise and lifts the right wheel of the toy car from the road surface (Fig. 5 (b)).

Further, if the above signal is continuously transmitted, as shown in FIG.
As shown in (c) and FIG. 5 (d), the toy vehicle is in a state of overturning, the body 2 is in contact with the ground, and the toy vehicle travels slidably. In this case, the plurality of protrusions 6 provided on the body 2 or the ring 7 provided on the rear wheel 4 are grounded on the road surface to protect the body 2 from damage and make the toy vehicle slippery. . As a result, car toys exhibit unpredictable behavior. That is,
This is an action like a stunt scene using a car such as a movie such as a car toy rotating.

Then, when a signal for operating the solenoid type electromagnet 41 is transmitted, the bar 10 is rotated, the car toy is raised (FIGS. 5 (e) and 5 (f)), and the normal traveling state is restored. (FIG. 5 (a)). Then, when the operation signal of the solenoid type electromagnet 41 is stopped, the force for attracting the moving iron core 43 disappears, so that the spur gear 34 returns to the position on the bearing 32 side by the elastic force of the spring 35, and is coupled to the worm gear 15. Comes off. Therefore, the turning of the bar 10 is stopped, and the elastic force of the spring 38 causes the bar 10 to move.
It returns to a position extending in the vertical direction with respect to the chassis 1.

The operation described above is performed by the solenoid type electromagnet 41.
If the motion signal of is continuously transmitted, it can be performed as a series of motions while the toy car is running. On the other hand, if the transmission is stopped on the way, the bar 10 can be stopped at an arbitrary position. Further, in the car toy of this embodiment, even if the car toy is running and overturned, the operator does not have to raise the car toy, and the bar 10 can be operated to raise the car toy by itself.

Next, a first modification of this embodiment will be described. FIG. 6 shows a side view corresponding to FIG. 2 described above. This first modification is a solenoid type electromagnet 41 of this embodiment.
Instead, a crank mechanism using a motor 61 is used. That is, this mechanism includes the first gear 62 connected to the rotating shaft of the motor 61 and the gear ratio for adjusting the gear ratio.
For example, the second gear meshing with the first gear 62 via the gear 63
The link 66 is connected to the eccentric position of the second gear 64, and the link 66 is connected to the arm 44. With this configuration, when the motor 61 is driven, the second gear 64 rotates, and the arm 44 is pulled through the link 66 (solid line arrow in FIG. 6) to press the spur gear 34, and the spur gear 34 and the worm gear 15 Combine with. When the motor is further rotated, the link 66 is pushed out in the opposite direction (dotted line arrow in FIG. 6) and the arm 44 is separated from the spur gear 34.

As described above, also in the first modification, the same operation as in the case of using the solenoid type electromagnet 41 of this embodiment can be obtained.

A second modification of this embodiment will be described. In the present embodiment and the first modification, the link mechanism including the solenoid type electromagnet 41 and the motor 61 is used, and the spur gear 3 is used.
By coupling 4 and the worm gear 15, the hexagonal shaft 33 is rotated using the driving force of the driving motor 11. Although not shown because it can be easily understood, in the second modification, the solenoid type electromagnet 4 is used.
1, the worm gear 15 and the spur gear 34 are omitted, and the motor is attached to the end of the hexagonal shaft 33. That is, the hexagonal shaft is directly rotated by the motor, and the bar 1
It turns 0.

Further, a third modification of this embodiment will be described. The third modified example uses the configuration of the second modified example, has two motors for driving an automobile toy, is connected to the left and right rear wheels, respectively, and omits the steering mechanism for the front wheels. It is a thing. In this configuration, the left and right driving motors have the same rotational speed, so that the automobile toy can be moved straight. Further, by changing the rotational speeds of the left and right drive motors, the toy vehicle can be turned to the wheel side having the lower rotational speed.

According to the third modification, since the steering mechanism for the front wheels can be omitted, the weight of the front part of the automobile toy can be reduced, and the bar 10 can be rolled over by the operation of the bar 10.
Furthermore, unpredictable behavior can be obtained.

In this embodiment, the solenoid type electromagnet 41 and the motor 61 are used as the operating member for operating the spur gear 34, but the present invention is not limited to this, and if the spur gear 34 can be operated, Any means may be used.

Although the preferred embodiments of the present invention have been described above, it goes without saying that various improvements and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention,
Since the bar to which the car toy can be turned over is provided, it is possible to obtain a radio-controlled car toy that can perform a motion like a movie stunt scene and can enjoy unpredictable driving.
